Abstract

A cable guiding device having at least one cable guiding pipe (conduit) of thermoplastic synthetic material, which cable guiding pipe has a cable guiding duct with a duct inner wall (which is circular in cross-section and has the pipe internal radius r), and which has sliding ribs which are arranged on the duct inner wall and are formed out of the thermoplastic synthetic material of the synthetic material pipe. The sliding ribs run at a predetermined rotation angle a with respect to the internal circumference. Contact surfaces having the rib contact width b result in a cable guiding pipe, which is arranged in a straight line, with a cable (which is to be inserted) at the contact points between the sliding ribs and the cable sheath of the cable which is to be inserted. The sliding ribs run in a corrugated shape and form reversing regions between sections having a constant rotation angle a. The rib contact width b, the number of sliding ribs which are distributed equidistantly over the circumference of the duct inner wall, the pipe internal radius r and the length LK of the rib contact sections between the reversing regions satisfy the equation Ar = 0.16 b<2>z LK. A defines the contact area of the cable sheath at the intersections with the sliding ribs in the rib contact sections. The angle g, measured in radians, of the pitch of the sliding ribs, measured on the duct inner wall, satisfies the equation g = ra/LK.

mezni kabli, pa tudi več njih ali svežnji kablov. Posamezni kabli so enožilni ali večžilni in imajo kabelski plašč, ki je iz gume ali umetne snovi. Drsna rebra imajo višino rebra več kot 0,1 mm, prednostno 0,3 do 3 mm. Med drsnimi rebri so nameščeni žlebi. Glede izraza vrtilni kot se opominja na teorijo vijačnice (primerjaj Hutte Des Ingenieurs Taschenbuch I, Theoretische Grundlagen, 28. izdaja, Ernst & Sohn Berlin, str. 157).cable bundles, as well as multiple bundles or bundles of cables. The individual cables are single-core or multi-core and have a cable jacket made of rubber or plastic. Sliding ribs have a rib height of more than 0.1 mm, preferably 0.3 to 3 mm. Grooves are located between the sliding ribs. As for the term rotational angle, it is recalled in the theory of helix (cf. Hutte Des Ingenieurs Taschenbuch I, Theoretische Grundlagen, 28th edition, Ernst & Sohn Berlin, p. 157).

Vijačnica je glede na to sledečs definirana: če se giblje premica tako, da vedno prereže čvrsto os pravokotno in da so razdalje, za kolikor se pomakne na premici čvrsta presečna točka na osi, sorazmerno kotom, za kolikor se vrti premica, potem opisuje vsaka njenih točk običajno vijačnico. Prej imenovanj, koti glede na začetno smer premice so vrtilni koti. Mera se nanaša na določen dolžinski odsek osi. Razen tega potekajo drsna rebra glede na notranjo steno kanala s preddoločenim dvigom. Tangens kota hoda na neki točki drsnega rebra je prvi odvod matematične enačbe vijačnice, ki odgovarja drsnemu rebru, na tej točki. Običajni premeri kablov leže v področju od 10 do 90 mm ter znašajo npr. 10, 28, 35 ali 90 m. Običajne cevi za vodenje kabla naprave za vodenje kabla po izumu imajo notranji premer v področju od 26 doThe helix is defined as follows: if a line moves in such a way that it always intersects the solid axis perpendicularly and that the distances by the intersection of the line are a solid intersection point on the axis in proportion to the angle that the line rotates, then describe each points usually a helix. Previously named, angles with respect to the initial direction of the line are rotational angles. The dimension refers to a specific length section of the axis. In addition, sliding ribs extend relative to the inner wall of the channel with a predetermined lift. The tangent of the walking angle at some point of the gliding rib is the first derivation of the mathematical equation of the helix corresponding to the gliding rib at this point. Typical cable diameters range from 10 to 90 mm, eg. 10, 28, 35 or 90 m. Conventional cable guide tubes according to the invention have an inside diameter in the range from 26 to

200 mm.200 mm.

Pojem naprave za vodenje kabla označuje npr. posamezne cevi za vodenje kabla (primerjaj DE 35 29 541 Al) toda tudi agregate cevi za vodenje kabla (primerjaj DE 32 17 401 Al). Cev za vodenje kabla oz. cevi za vodenje kabla naprave za vodenje kabla sprejmejo posamezne kable ali svežnje kablov, ki jih je treba uvesti s potiskanjem ali vlečenjem. Pri znani napravi za vlečenje kabla (DE 35 29 541 Al) imajo drsna rebra, glede na os kanala za vodenje kabla in v smeri osi kanala za vodenje kabla, konstantno smer. Potekajo primeroma v obliki vijačne spirale kakor tudi po vsej dolžini naprave za vodenje kabla v smeri levega ali desnega vrtenja z enakim vrtilnim kotom.

Conduit for hose or cable. cable guides The cable guides accept the individual cables or cable bundles to be introduced by pushing or pulling. For known cable drawing devices (DE 35 29 541 Al), the sliding ribs have a constant direction relative to the axis of the cable guide channel and in the direction of the axis of the cable guide channel. They occur, for example, in the form of a helical coil, as well as along the entire length of the cable guidance device in the direction of left or right rotation with the same rotational angle. The friction resistance held by the cable or

I sveženj kablov pri uvajanju v takšno napravo za vodenje kabla, se s temi drsnimi rebri znatno zmanjša. To se je bbneslo pri mnogih primerih uporabe in olajšalo potiskanje notri ali uvlečenje kabla oz. svežnja kablov. Za oba ukrepa se uporablja v okviru izuma izraz uvlečenje. Lahko se zgodi glede na obliko kabla ali svežnja kablov, da nastanejo iz medsebojnega delovanja kabla in svežnja kablov z drsnimi rebri moteči vplivi, namreč da delujejo tordirajoče sile na kabel oz. sveženj kablov in povzročijo moteče in znatno zavirajoče tordiranje kabla ali kabelskega svežnja. Pri tem se lahko kabel ali kabelski sveženj na drsnih rebrih celo povzpne. Ti moteči vplivi se lahko zmanjšajo, če, kot je prav tako znano, namestimo drsna rebra glede na os kanala za vodenje kabla in v smeri osi kanala za vodenje kabla z izmenjajočo se smerjo (DE 40 31 733 Al). Izmenjajoča se smer pomeni, da je smisel vrtenja drsnih reber različen, npr. enkrat z leve na desno, enkrat z desno v levo. Drugače izraženo je vrtilni kot enkrat pozitiven, enkrat negativen. Pri tem lahko izkazujejo drsna rebra poleg tega v smeri osi kanala za vodenje kabla po odsekih različen hod.

This has been the case in many applications and has made it easier to push in or pull in a cable or cable. bundle of cables. For both measures, the term indentation is used in the context of the invention. Depending on the shape of the cable or the bundle of cables, it may occur from the interaction of the cable and the bundle of cables with sliding ribs that have interfering effects, namely that the torsional forces act on the cable or cable. bundles of cables and cause disruptive and significantly inhibitory tording of the cable or bundle. In this case, the cable or wiring harness on the sliding ribs can even be climbed. These interfering effects can be reduced if, as is also known, sliding ribs are positioned relative to the axis of the cable guide channel and in the direction of the axis of the alternating direction cable guide channel (DE 40 31 733 Al). The alternating direction means that the sense of rotation of the sliding ribs is different, e.g. once from left to right, once from right to left. In other words, the rotation is once positive, once negative. In addition, sliding ribs may also exhibit a different stroke in the direction of the axis of the cable guide channel.

Iz tornega medsebojnega delovanja kabla oz. svežnja kablov z drsnimi rebri rezultirajoče sile nič več ne povzročijo motečega tordiranja kabla oz. svežnja kablov ter se poplnoma odstranijo, odvisno od oblikovanja. Kljub temu pa se iIt is no longer the case with the cable guides that there is no longer any interfering torsional force on the cable or the bundle of cables that must be pushed in or retracted. From the friction interaction of the cable or. the bundle of cables with the sliding ribs of the resulting force no longer causes the cable to be disturbed or disrupted. depending on the design, the cable bundles are removed. Nevertheless, i

Uporabiti se morajo odgovarjajoče naprave. To vse velja tudi tedaj, če potekajo pri tej znani izvedbeni obliki v posebnem slučaju brez posebnega vodenja in izoblikovanja drsna rebra v obliki kačaste linije (DE 40 31 783 Al, sl. 1, 4 in 5).they must use, when retracting the cable or the wiring harness, into the cable conduit, non-negligible linear retracting forces to overcome the equally linear friction resistance in the longitudinal direction of the conduit. Appropriate devices must be used. This is true even if, in this particular embodiment, in a special case, no sliding ribs are formed in the form of a snake line (DE 40 31 783 Al, Figs 1, 4 and 5) in a special case.

Izum sloni na nalogi, tako urediti napravo za vodenje kabla uvodoma opisane sestave, da so sile uvlečenja' pod vsemi pogoji obratovanja uvlečenja in tudi tedaj, ko se polaga naprava za vodenje kabla v loku, ekstremno majhne.The invention is based on the task of arranging the cable guidance device of the composition described in the beginning, so that the pulling forces' are extremely small under all conditions of the pulling operation and even when the cable guidance device is placed in the arc.

Preddoločena mera vrtilnega kota se pri tem nanaša na dolžinski odsek osi kabelskega kanala med področji.and lies numerically in the range of 0.001 to 1.2 rad, with r selected in the range of 12 to 100 mm and L μ, in the range of 500 to 10,000 mm as well as the introduced cables exhibiting an outer radius in the range of 5 to 45 mm. The predetermined measure of rotational angle here refers to the length of the axis of the cable channel axis between the areas.

Področja zasuka so pri drsnih rebrih, ki potekajo v odvijanju notrane stene kanala v ravnino sinusno, najvišje točke valovitih vrhov oz. najnižje točke dolin vrhov sinusnih krivulj. Področja zasuka postanejo tedaj točke zasuka. Značilnosti 1) v izvedbeni obliki s področji zasuka, skrčenimi v točki zasuka, je, kot je uvodoma opisano, po sebi znana. Lahko se pa v področja vrhov iThe areas of rotation are the highest points of the undulating peaks or the sliding ribs, which extend in the unscrewing of the inner wall of the channel into the plane of the sine. the lowest points of the valleys of the peaks of the sine curves. The turning areas then become turning points. Characteristics 1) In the embodiment, with the areas of rotation shrunk at the point of rotation, it is known as described above. It can, however, be in the areas of peaks i

I kanala potekajoči odseki drsnih reber vklopijo vmes ter določajo razmeroma dolga področja zasuka. Površine dotika plašča kabla imajo s posameznimi drsnimi rebri v tlorisu več ali manj romboid··no obliko, katere geometrija je določena s širino rebrnih dotikov, tj. širina drsnih reber na dotikalni točki na kabelskem plašču in s potekom drsnih reber. Za nadaljnjo razlago v prejšnjem obravnavanega nauka za tehnično delovanje pojavljajočih se pojmov se navaja na sl. 1 in njen opis.In the first channel, the running sections of the sliding ribs engage in between and determine relatively long areas of rotation. The contact surfaces of the cable jacket have a more or less rhombic shape with the individual sliding ribs in the floor plan, whose geometry is determined by the width of the rib contacts, i.e. the width of the sliding ribs at the touch point on the cable jacket and with the passage of the sliding ribs. For further explanation in the previously discussed doctrine for the technical operation of the emerging concepts, it is referred to in FIG. 1 and its description.

Izum izhaja iz spoznanja, da se lahko doseže pri v prejšnjem določenih in z merami označenih ceveh za vodenje kabla in kablov znatno zmanjšanje uvlačilnih sil, če se poskrbi za to, da se lahko nadomesti pri pojavu moteče velikih uvlačilnih sil v povezavi z deli uvlačenja, ki se morajo izvesti, suho trenje s trenjem, ki se približuje trenju mazalnega sredstva, ki izkazuje, kot je znano, bistveno manjše torne koeficiente kot suho trenje. V ta namen se vendar po izumu ne uvaja posebno mazalno sredstvo. Pač pa se po postopku, ki spada k izumu, za uvlačenje kabla izbere prednostno takšno hitrost uvlačenja in/ali potisno hitrost uvlečnega kabla ali kabelskega svežnja, da nastopi zvišanje temperature na dotikalnih ploskvah, kar presenetljivo zmanjša torni upor. Prednostno se postopa tako, da se idotikalne ploskve zaradi torne toplote natalijo in se vzpostavi zaradi talilnega iThe invention is based on the realization that, in the previously defined and dimensioned cable and cable guides, significant reductions in retracting forces can be achieved, provided that they can be compensated for by disturbing large retracting forces in connection with retractable parts, to be performed, friction with friction approaching the friction of a lubricant which exhibits, as is known, significantly lower friction coefficients than dry friction. For this purpose, however, no special lubricant is introduced according to the invention. However, according to the process of the invention, the cable retraction speed and / or the thrust speed of the retractor or the wiring harness is preferably selected for retracting the cable, in order to increase the temperature on the touch surfaces, which surprisingly reduces the friction resistance. Preferably, the idiotic surfaces are deposited due to the friction heat and set up due to the melting point.

toka stanje pravega mazalnega trenja. Ta možnost je bila doslejflow state of true lubricating friction. This option has been so far

I spregledana. Presek drsnih reber je pri tem znotraj preje navedenih meja dalekosežno poljuben. Po izumu so podani številčni parametri tako urejeni, da se lahko vedno in brez težav doseže stanje mazalnega trenja, če je izdelana naprava za vodenje kabla iz za takšne predmete običajnih termoplastičnih umetnih snovi in če imajo kabli običajne kabelske plašče in tudi običajno maso na dolžinsko enoto, če obstoji po izumu tudi ta možnost, je vendarle v okviru izuma, da se namesti mazivo v žlebičastih poglobitvah med drsnimi rebri. Potrebno pa to vendar ni. Prav tako imajo lahko kabelski plašči oslojitev, ki deluje kot drsno sredstvo. Razume se, da se povečajo pri napravi za vodenje kabla po izumu uvlačilne sile glede na absolutno velikost sorazmerno z dolžino naprave za vodenje kabla. To velja tudi potem, če se uredi po opisanem postopku mazalno trenje s stalitvijo drsnih reber, oziroma bolj natančno grebenov drsnih reber. V okviru izuma je tudi, če se uvleče tako počasi in previdno, da ni potrebna vzposI tavitev mazalnega trenja in se tudi ne vzpostavi.And overlooked. The cross-section of the sliding ribs is far from arbitrary within the boundaries mentioned above. According to the invention, the given numerical parameters are arranged in such a way that the condition of lubricating friction can be easily and easily reached if a cable guide device is made from such conventional thermoplastic plastics and if the cables have conventional cable sheaths and also a normal mass per unit length , if this possibility also exists according to the invention, it is, however, within the scope of the invention to place the lubricant in grooved grooves between the sliding ribs. This is not necessary, however. They can also have cable sheaths that act as a slide. It is understood that, in the case of the cable guidance device according to the invention, the pulling forces are increased in relation to the absolute size in proportion to the length of the cable guidance device. This is true even if the lubricating friction is arranged according to the described procedure by the placement of the sliding ribs, or more precisely the ridges of the sliding ribs. It is also within the scope of the invention to retract so slowly and carefully that no lubrication friction is required and is not recovered.

če je tudi presek drsnih reber dalekosežno poljuben, je odlična izvedbena oblika, pri kateri izkazuje notranja stena kabelskega kanala med sosednjimi drsnimi rebri proti kabelskemu kanalu konkavno obliko žleba, ki se steka na obeh straneh v greben drsnih reber.if the cross-section of the sliding ribs is arbitrarily arbitrary, it is an excellent embodiment in which the inner wall of the cable duct between the adjacent sliding ribs against the cable duct shows a concave groove projecting on either side into the ridge of the sliding ribs.

i če uresničimo nauk izuma, nastane za napravo za vodenje kabla s cevmi za vodenje kabla običajnih premerov večje število izoblikovanj, ki imajo poseben pomen. Navedeni so v sledeči tabeli:i If the teachings of the invention are to be realized, a large number of shapes of particular importance are created for the cable guide tube with the usual diameter cable guides.
